.different parts of machinery.

An important objectief this invention is to provide a grease gun which is particularly adapted for use in connection with automobiles or the like for quickly and easily lubricating parts of the same which are ordinarily more or less inaccessible.

A further object of this invention is to provide a lubricator of the above mentioned character, which is well adapted for use inconnection with a non- Huid lubricant, for enabling the operator to use the device without getting his hands soiled by the lubricant.

A further object of the invention is to provide a lubricator formed in separable parts, whereby it may be quickly and easily filled with the lubricant.

A further object of the invention is to provide a lubricator having manually operated means to compress the lubricant, and novel discharge means for 'conducting such compressed lubricant to the parts to which the same is to be applied.

A further object of the invention is to provide a device of the above mentioned character, having a lflexible discharge conduit provided with'a tip having swivel connection therewith, whereby the lubricant may be easily applied to parts of machinery which are ordinarily inaccessible.

Other objects and advantages of the invention will be' apparent during the course of the Jfollowing description,

In the accompanying drawings formin a pant of this specication and in which like numerals are employed to designateV like parts `throughoutthe same, Figure `1 is a front elevation of the lubricator, Fig. 2-is a plan view of the same, Fig. Sis a central vertical longitudinal sectional view throughl the' same, and, Fig. 4 is a horizontal sectional view takenon line 4-4 of Fig. v1.

In the v.drawings wherein for .the purpose of illustration, we have shown Val?'referred clamping bolts carry embodiment of our invention, the numeral 1 designates a base upon which is formed a preferably cylindrical upst-anding shell or caslng 2, having its lower end in communication with a discharge port 3, which leads into a; pipe coupling 4 or the like. Suitably connected with the pipe coupling 4 is a exible metallic discharge ipe or conduit 5, to the upper end of which is secured a metallic sleeve 6, as shown. This metallic sleeve has its outer or upper end provided with an outwardly extending annular iange 7, to'k be engaged. by an inwardly extending tlangecS carried by a collar 9. Disposed within the collar 9 is a ball 10, having a diametrically arranged openingdl formed therethrough for receiving a tip or tube 12 which is'sol dered or otherwise rigidly connected with the ball 10 within the opening 11. The ball 10 is free to turn in all directions within the collar 9 and is held therein by a ring 13, which is externally screw-threaded to en gage with internal screw-threads of the col- `Vlar 9. It is thus seen that the tip or tube 12 has a universal .or ball and socket connection with the flexible pipe 5, which enables the operator to supply lubricant to parts of machinery which are ordinarily more or less inaccessible;

The upstanding shell or casing 2 is provided at its upper vend with a preferably rectangular horizontal outwardly extending flange 14, provided at its corners with slots- 15, for receiving swinging clamping bolts 16,' provided with apertured heads for receiving pins 17, serving to pivot-ally connect the clamping bolts with the flange 14. Adapted to be movably mounted upon the upper flanged end 14 of the shell or casing 2 is a preferably rectangular head 18, which is provided at its corners with slots 19, adapted' to register with the slots 15 and to receive therein the clamping bolts 16. The on their screw threads nuts 2Q. It is thus seen that the head 18 is securely held Aupon .the flanged end 14 ofthe shel1or casing.2 and may be readily removed therefromwhen desired. The head 18 has-a preferably cylindrical opening or recess-21-formed therein, which is adapted to register witlh .the opening of the shell Vflange 22 itting within an annular recess is thus seenYV that the operatingscrew 28 is capable of moving longitudinally through nection with a plunger 31, provided uponk the opening 27 but cannot turn therein.v At its lower end the operating screw has conits periphery with an annular groove 32, for receiving a packing ring 33. Attention is called tothe fact that when the shell or casing 2 is to be filled with the, non-fluid lubricant, the operating screw 28 is moved s outwardly suliiciently`to bring the plunger 31 into the recess 21, subsequently to which the head 18 may be removed. The shell or casing 2 is then iilled with the lubricant and the head 18 returned to its operative position. When the plunger 30 is moved downwardly to compress Lthe lubricant, it is obvious that the packing ring 33 is not allowed to move out of its annular groove32.' Aside' from this advantage, the plunger receiving space 21 of the removable head 18 allows the shell or casing 2 t-o be completely filled with the non-Huid lubricant.

The operating screw 28 is raised and lowered by means of a bevel gear 34, having aI screw -threaded opening formed therethrough vfor receiving the operating screw 28, such bevel-gear operating in slidableengagernent with the horizontal portion 25 of the bracket 24. The bevel-gear 34 is rotated by a second bevel-gear 36, which is rigidly mounted upon a rotatable shaft 37, extending through an .opening 38 formed in the vertical portion 26 of the bracket 24. The horizontalshaft 37 is provided atits outer end with an enlarged head 39, having an opening-formed therethrough for receiving a crank-arm 40. The crank-arm 40 islongi- `tudinally adjustable with relationv to the head-39 and is clamped thereto in adjustment at desired 'positions by a screw 41 orY the like. At one end the crank-arm 40 carries a freely rotatable handle 42 and atits opposite end it carries a head 43, .as shown.

Mounted upon one side of the shell or casing2 is a vertical plate 44, provided with two scales 45 and 46, having any desired graduations. The scale 45 is employedto indicate the amount of lubricant inthe shell or casing 2, while the scale 46 is employed to indicate the amount of lubricant which has been removed from the shell or casing. Co-

operating with these scales is a depending indicator-rod 47 passing through an aper- -slots 19, whereby the head 18 may be retured guide bracket v48 and connected at its `upper end with the operating screw 28, as

shown at 49.

The operation of 'the device is as follows VVhen it is desired to fill the shell or 'casing 2 with the non-fluid lubricant, the

operator takes hold of the handle 42.and 10-v -tates the same, which rotation is imparted to the bevel-gear 36 andy then to the bevelf gear 34, which in turn moves the operating screw 28` upwardly until the plunger 31 fits within the opening or recess 21. The nuts 20 are now turned so that the clamping bolts 16 may be swung downwardly out of the moved from the lianged upper end 14 of the shell or casing 2.l It is thus seen thatall of theoperating parts of the device are carried by or casing 2 may now be filled with the nonfluid lubricant. -The head 18 may now be returned to its normal position and the clamping bolts 16 placed in the slots 19,: subsequently toffwhich the nuts 20 are` turned to @securely clamp the head 18 to the this removable head 18. The shell u forward end 14. The tubeor tip 12 is now. placed in suitable proximity to the part or parts to be lubricated 'and the crank-arm 40 is turned, causing the plunger 31 to descend and compress the non-fluid lubricant, cansing it to discharge through the flexible vpipe and tube or tip 12. The scale 46 will in;

dicate the amount of the lubricant thathas been discharged from the casing'or shell 2 while the scale 45 will indicate how much of the non-Huid lubricant remains.

It is to be understood that the form of the invention herewith shown 'and described is` to be taken as a preferred example of the same and that certain changes in the shape,

size, vand arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the4 sub-` joined claims.
